Ubuntu announced its 17.04 (Zesty Zapus) release almost 9 months ago, on April 13, 2017. As a non-LTS release, 17.04 has a 9-month support cycle and, as such, will reach end of life on Saturday, January 13th.

At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 17.04.

The supported upgrade path from Ubuntu 17.04 is via Ubuntu 17.10. Instructions and caveats for the upgrade may be found at:

https://help.ubuntu.com/community/Upgrades

Note that is NOT patched against Meltdown and Spectre vulnerabilities due to the End of Life timing. Users are advised to upgrade to Ubuntu 17.10 and install the updated kernel packages.

Development of a complete response to the highly-publicized Meltdown and Spectre vulnerabilities is ongoing, and due to the timing with respect to this End of Life, we will not be providing updated Linux kernel packages for Ubuntu 17.04. We advise users to upgrade to Ubuntu 17.10 and install the updated kernel packages for that release when they become available.

When you right-click on blank area in Nautilus or Ubuntu Desktop, you’ll find there miss the ‘New Document’ option in the pop up menu.

It’s easy to re-enable the option in Nautilus context menu. As it prompts in Templates folder, simply create an empty document in Templates, the file name will be displayed as sub-menu option of ‘New Document’ menu.

While you can’t create a file via the context menu, do it via touch command:

1. Open terminal by pressing Ctrl+Alt+T or searching for “Terminal” from start menu. When it opens, run command:

touch ~/Templates/Untitled\ Document

This command creates an empty file called ‘Untitled Document‘ in the Templates folder.

Tip: the backslash in the code tells that the space following it is part of the filename since the shell treats whatever comes after a space as a separate argument.

2. Now right-click on your desktop or blank area in Nautilus browser, the pop up context menu will look like:

May need to restart if you have not update your system for a long time.

6. (Optional) Useless packages and software libraries may take a few more minutes upgrading your system. For me, Ubuntu Kylin and Plasma Desktop libraries take quite a few minutes in the upgrading process.

After all, launch Update Manager via the command below and it will prompt that Ubuntu 17.04 is available after checking for updates:

sudo update-manager -d

Click the Upgrade and confirm in the next dialog, follow the wizard util done.
